.CAR CONSTRUCTION.

Application led December 1Y0, 1921. Serial No. 521,292.

To all whom t mary concern.'

Be it known that I, ARGYLE CAMPBELL, a citizen of the United States,residing at Chicago, in the county of Cook and State of `Illinois, haveinvented a certain new and useful Improvement in Car Constructions, ofwhich the following is a full, clear, concise, and exact description,reference being had to the accompanying drawings, forming a part of thisspecication.

This invention relates to improvements in car construction.

In dump cars, considerable diiiiculty has heretofore 'been experiencedinpreventing. tearing out and corroding at certain points sheet metalparts of the car construction to thereby prevent the same from tearingout. Another and more specific object of the invention is to provide acombined Hoor stiffener hinge butt and corner brace for dump cars.

In the drawings forming a part of this specification, Figure 1 is a sideelevational view of a portion of a drop bottom dump car, showing myimprovements in connection therewith. Figure 22 is a vertical, sectionalview, taken transversely of the car, from the side to the center stillthereof and corresponding substantially to the section line 2-2 ofFigure 1. Figure 3 is a top plan view of the improved combined licorstiiener hinge buttv and lcorner brace, detached, such as shown inFigures 1 and 2. Figures 4 and 5 are detail, transverse sections of thecombined stifiener and -brace and corresponding to the section lines 4-4and 5-5 respectively of Figure And Figure 6 is af'view 'similar'toFigure 2 illustrating my improvements applied to a slightly differenttype of car. c

Referring to the construction illustrated in Figires 1 to 5 inclusive,10 denotesone in Figures of the floor sheets of the car, 11 the outerside hopper sheet, 12 the inner side hopper sheetand 13 one of thechannels of' the center'sill girder. l

In the particular type of car shown, two hinged bottom doors 14f 14 areemployed, the same having their free edges `meeting when the doors arein closed position. Each of said doors isl adapted to be hinged about anaxis extending transversely of the car at the free edge of thecorrespondin bottom sheet, by means hereinafter descri d.

As shown the outer side hopper sheet 11 I is secured along its upperedge .to the side wall 15 of the car, is then extended downwardly andmwardly as indicated at 16, and

thence downwardly vertically as indicatedl at 17 the bottom edge of saidsheet 11 where engaged by the doors, being formed with an outwardlyextending ange 18 which is then bent vertically ldownward as indicatedat 19 Y 1n a plane4 outwardly offset from the plane of the section 17,to thereby proyide a better seal for the door when the latter is inclosed position. The inner side hopper sheet 12 at the lower portionsdefining the hopper dis` charge opening, extends vertically as shown inFigure-2 and along its lower edge is ared outwardly as indicated at 20and thence downwardly in a verticalplane asindicated at 21, similar tothe other outer sideA hopper sheet 11. As clearly. indicated in Figure1, the lower edge portions of the side hopper sheets, between the hingejoints, con-- verge Vdownwardly to conformy to the inclined positions ofthe doors when the latter are in closed position.`

To stiien and reinforce the lower transversely extending edge 22 of= thefloor sheet 10 alongy the line of the hinge connection of the door, Iemploy a combined floor stiffener and hinge butt designated generally bythe reference character A. As best shown 3, 4 and 5, v`said combinedstiffener and hinge butt is provided with a main web 23 extending underand for the full width of the bottom sheet 10 and rigidly securedthereto as by the series of rivets 2li--V 24. Along the lower edge, thatis, the edge substantially ush with the edge 22.0f the ior shee`t 10,said stiener and hinge butt A is formed with a relatively narrowdepending iange-'25 extending the full length of the stiener asbestshown in Figure. 3. Along the opposite edge of the main web 23,

iro

the member A is provided with another downwardly extending flange26,said flange 26 extending the full length of the member A. The twoflanges 25 and 26 are extended at right angles to the main web 23, thatis perpendicular to the inclined oor'sheet 10. The wider flange 26 maybe additionally strengthened by a narrow lip-'27 extending at rightangles to the flange 26 and away therefrom, parallel to the main web23.-

intermediate its ends and at suitable points corresponding to the hinge)butts secured to the door, the member A isprovided with pairs ofdepending, relatively heavy, spaced ears 28-28 perpendicular to the mainweb 23 and also perpendicular to the main flanges 25 and 26. rlhe earsare provided with alined openings 29 adapted to accommodate heavy headedhinge pins 30- 30 which also extend through suitable eyes 31 formed onthe double-ever hinge straps 32 secured to the under sidi` of the door.

Opposite each pair of ears 28, the casting A is additionally reinforcedby web sections 23a continued in the plane of the web 23, said websections 23a being in turn braced by triangular shaped flanges 33-33extending in vertical planes and depending from v the web sections 23a.

`With the construction of combined floor stifi'e'ner and hinge buttabove described, it is evident that the same thoroughly braces andreinforces the lower or free edge of the floor sheet and serves toprevent the latter from bending under the loads imposed thereon at thetwo points of support for the door. The member serves the doublefunction of the usual angle iron reinforcement and independent hingelugis, thus minimizing the cost of application, and furthermore. a veryeflicient seal is obtained betweenv the flange 25 of thel member A andthe edge flange-MaEl of the door.

Due to the outward langing of the side hopper sheets 11 and 12'at pointsopposite the ends of the line of the free edge 22 of the bottom sheet10, it will be noted that corners of peculiar form are produced in thebending and forming of thesheet which, if not properly taken care of,will easily tear `under the loads imposed thereon and are'alsoparticularly subject to corrosion due to the inherent weaknesses set upin the metal at these points because of the stretching and deformationthereof.

To compensate for the necessarily weak structure developedat the pointsmentioned in the side hoppersheets, l form the member A with additionalend flanges to conform to and fit over the different portions of theside hopper sheet. At each end, the member A is provided with avertically extending liange 34 which ts against and is riveted to thevertical section 17 or 12 .of the corresponding side hopper sheet. rlheend portion of the member A is additionally provided with an outwardlyextended flange section 35 fitting over the top of the flange section 18or 2() of the corresponding side hopper sheet 11 or 12. At each end themember A is additionally provided with a downwardly extending flangesection 36 fitting over and againstthe corresponding verticallyextending flange section 19 or 21 of the respective side hopper sheet 11or 12. As best shown in Figure 1, the flange sections 36 of the member Aare sufficiently extended to cover the ends of the joint formed betweenthe hinge edge of the door and the free edge of the bottom sheet 10,thus providing an additional seal to prevent escape of any of the loadas well as strengthening the sheet metal at these points. As will beunderstood, the outwardly extended flange sections 35 of the member Aconform in slope to the slope of the corresponding flangev sections 18or 2O of the side hopper sheets, as clearly shown in Figures 1 and 2.The flange sections 34, 35 and 36 at each end of the member A are braced.by means of ribs 37 extending in planes at right angles tothe flanges34 and 36.

The construction illustra-ted in Figure 6, so far as concerns thecombined floor stiff'- ener, 'hinge butt and corner brace A, is the sameas that shown in the other figuresexcept that the corner brace featureis employed at one end only, viz: the outer end, inasmuch as the innerside hopper sheet 112 has no offset flange sections and is otherwisebraced where it joins with the floor sheet by means of an angle iron 38riveted to the side sheet 112 and the lower flange of the center sillchannel 113.

l have herein shown my improvements as the same would be applied to twodifferent types of dump cars, but it is obvious that different othertypes of tions of the brace to conform to the particular formations ofthe floor and side hopper sheets of the car, without departing from thespirit of the invention. it will also, be observed that my invention,may be embodied in corner braces inade separate from the floorstill'eners and hinge butts. All changes and modifications arecontemplated that come within the scope of the claims appended hereto.
